I checked our DNS and we do have one of these zones for each C-class.
For example, our site is 209.19.77.6
In "Domain Name Service Manager" (MS DNS Manager)
I do have the following zone...
77.19.209.in-addr.arpa
If I double click on that, I have PTR records for each and every
A Record for each and every domain in that C class, including cydian.com
Any idea what else might prevent the reverse lookup? I'm
stumped, and I know that emails are being bounced by the likes of AOL
because they can't do the reverse.
Mega Kudos to whoever has a clue for me on this one.
THANKS!!!
